CVE-2026-96871

The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data type' parameter in all versions up to, and including, 2.4.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable on any board configured with the default write level=0 (guest posting) and editor type=N settings, which are the out-of-the-box defaults for newly created boards.
